Idle surging and throttle not operating

[BeToney]

I was an hour and a half into a ride this morning, the bike was running absolutely flawlessly one moment and a second later it started surging and chugging as it came to a stop on the side of the road. 
The motor will turn over and start but the idle surges up and down quickly and the throttle does absolutely nothing.  The gear indicator on the screen just shows a dash - (DCT model) and it will not go into gear.

The fluctuating idle happened to my truck years ago and it was the TPS, trying a forum search, some of the results mentioned a MAP sensor?  Anyone have knowledge of these symptoms or possible TPS or MAP issues?  The dealer is booked until the end of the month before they can even start diagnosing the issue, let alone ordering parts or starting repairs.

Thanks in advance.

Agree, sounds like a TPS issue to me.

**Update**  This ended up being an embarrassing user error. 
I decided to re-check the last maintenance I performed before the incident, which was cleaning the air filter.  Upon opening the airbox, I was shocked to find a blue paper towel inside the intake snorkle.
While cleaning the air filter a few weeks prior, I carelessly left a paper towel in the airbox and it got sucked into the intake of cylinder #1 and jammed the butterfly valve.   
Everything put back together and the bike operated normally on a road test.  After almost 50 years of wrenching on cars and bikes, that's the first time I have ever been so inattentive when putting something back together.  Lesson learned.

No embarrassment BeTony, just an error. Great you got it sorted.

Nice to see an honest reply and good outcome. We've all done similar.

@thetrecker and @Pickaxe  Thanks for the kind replies, hopefully my mistake can be a lesson for others.

I know this topic is a bit old but it reminded me of something funny I just have to recount. About 15 years ago there was a guy selling drugs from a workshop in the same complex as mine. He used to get raided regularly but somehow knew when it was going to happen so nothing was found for a long time. Anyway one day he decided to hide a big pile of cash in the air cleaner housing of of his old turbo diesel landcruiser. Unfortunately he put it on the clean air side of the element. The result was catastrophic and poetic justice. There were pieces of notes all through the intake manifold and into the combustion chambers, chopped up by the turbo blades and the turbo ended up completely choked and locked up with paper. A few of us saw the vehicle afterwards with the remaining notes in the air cleaner and pissed ourselves laughing. Couldn't have happened to a nicer bloke LOL. He disappeared not long after.
